Specification of Letters Patent.

Patented Jan. 14., 1919.

Application filed October 29, 1917. Serial No. 199,032.

To all whom it may concern:

Be it known that I, NATHANIEL S. MON- ROE, a citizen of the United States, residing at Arthur, in the county of Douglas and State of Illinois, have invented certain new and useful Improvements in Drags, of

which the following is a specification.

This invention relates to road drags of the general class or type shown, for instance, in Letters Patent of the United States, No. 1,176,591 granted to me on March 21, 1916.

One object of the present invention is to construct a machine of the class described which will be made entirely of metal and in a light and durable manner, material being economized as far as consistent with proper strength and durability.

A further object of the invention is to construct a drag of the class described which may be utilized as a scraper or as a smoothdevice by simple adjustple and improved manner.

Further objects of the invention are to simplify and improve the general construction and arrangement of the detailed parts of the device.

IVith these and other aims in view which will readily appear as the nature of the invention is better understood, the same consists in the improved construction and combination of parts which will be hereinafter fully described and particularly pointed out in the claim.

In the drawings hereto annexed there has been shown a simple and preferred embodiment of the invention; it being, however, understood that no limitation is necessarily made to the precise structural details therein exhibited, but that changes, alterations and modifications within the scope of the appended claim may be resorted to when desired.

In the drawings:

7 V Figure 1is a perspective view of a drag constructed 1n accordance. with the invention. Fig. 2 is same.

a vertical, sectional 'view of the Fig. 3 is a sectional view similar to Fig.

2, but showing the device arranged for smoothing or troweling. v

Fig. 4 1s a sectional detail v1ew taken on the line 4-4 in Fig. 1.

Fig. 4 is a sectional, detail view taken on the line 4-4, in Fig. 1.

Figs. 5 and 6 are detailed views of the draft chain and the draft link.

Fig. 7 is a sectional, detailed view illustrating a modification.

Fi 8 is a front view of a portion of Fig. i.

Fig. 9 is a detail view illustrating a further modification.

Corresponding parts in the several views are denoted by like characters of reference.

In the construction of the improved machine there are included two angle bars 15,

16, of iron or steel which constitute respectively the front and rear bars of the drag. On the vertical web of the front bar, which faces toward the front, is riveted or otherwise secured a scraper blade 17, the working edge of which extends below the horizontal web of said angle bar. Riveted or otherwise secured on the under face of the horizontal web of the rear angle bar is a troweling plate 18. The blade 17, and the plate 18, are each of a length substantially equal to the length of the angle bars. It may also be stated that while the horizontal web of the front angle bar is of sufficient width to constitute a troweling memher, the rear'angle bar is of relatively small dimensions, the horizontal web being comparatively narrow and utilized merely for the attachment of the troweling plate 18.

The front and rear bars 15, 16, are connected together by angle bars 19, of which three have been shown, one being located near each end and one about midway between the ends of the front and rear bars. The angle bars 19, are riveted or otherwise secured on the horizontal web of the rear bar 16; firmly secured on the front bar 15, are angle blocks or lugs 20, with which the vertical webs of theangle bars 19, are pivotally connected by means of bolts 21. The angle bars 19 are bent upward about midway between their front and rear ends as seen at 2:2, thereby causing the forward portion of the plate 18, to be tilted upwardly as clearly seen inFigs. 1, 2 and 8 of the drawings-1 The pivotal connection of the from bar 15, with the angle bars 19, will permit the said front bar to be tilted to theposition illustrated in Figs. 1 and 2 where the scraper blade 17, will engage the surface of the ground, and also to the position illustrated in Fig; 3 Where the said blade is supported above the ground while the horizontal web of the angle bar 15, is in troweling engagement with the ground.

Firmly secured on the vertical web of the angle bar 15, is a vertically disposed angle bar 23, the same constituting an upright with which a lever 24 is firmly connected, said lever being secured by rivets 25,.0n the rearwardly extending web of said angle bar 23. Another short angle bar 26, constituting a foot piece, .is secured on the laterally extending web of the angle bar 23.. It is evident that by means of the lever 24, the front angle bar may be tilted about the axes of the boltsj2l.

For the purpose of retaining the partssecurely at various adjustments, various means of slightly different nature may be employed. In Fig. 2 a bar 27, has been shown, said bar being pivoted on the middle angle bar 19, and said bar extending through a slot 28, which maybe formed by a keeper 29, secured 011 thelever, said'bar having notches 30, adapted for engagement with a pin 31, disposed transversely in the slot. A spring 32 has been shown whereby the notched bar is retained in engaging position, and the said bar is provided with a foot piece or treadle 33, extending at an angle thereto. In Fig. 3 the spring32, is omitted. In Fig. 7 both the spring 32 and the foot piece 33, are omitted and the keeper, here designated by 28, is. provided with rounded engaging faces 34, for the notched bar which, in this instance, has the notches 30 formedin the upper instead of the lower edge thereof, saidnotches beingengaged by r a latch 35, pivoted on a lug 36, extending from the lever 24, as best seen in Fig. 8. In

Fig. 9 a similar construction is shown eX- cept that the lug 36, on which the latch 35 is pivoted, extends from the keeper.

A seat support is provided, the sameconsisting of downwardly'diverging, legs 37,.the

lower ends of whichare-secured on the vertical web o'ftherear angle bar 16, a third leg 88, being connected at its upper end with theupper ends of the legs 37 and at its lower end with the middle angle bar 19; The seat 39, is secured by a'fastening member 40, to the upper ends of theseverallegs.

A draft chain 41, is terminallyconnected the angle bars 19. at the two ends of the;machine,.are connected with the lugs 20.. The draft chain extends above the upper edge ofthescraper edge 17, and it, carries a. draft link 5L2, the eye or opening. of which isof keyhole: shape so that in one position. of said link, as seen menace tween two links of the chain, thereby retaining the draft link in adjusted position as seenv in Fig. 1. It will be readily seen that by proper adjustment of the draft link, draft may beap'pli'ed' midway between the ends of the front bar 15 thereby causing said front bar to be presented at right angles to the line of draft while, by moving the draft link'toward either end, a slantingv position with respect to the line ofdraft may be ,obtained. V g

It will be readily seenthatwhen the lever 24 is disengaged from the notched-latch bar, the operator, by placing his feet on the foot piece 26, and using. his hands for manipulating the lever, may forcibly tilt the front bar 15, of the machineto the most desirable position for operation, such positionbeing illustrated in Figs. 2 and 3 may be actuated by the treadle 33. In the. forms shownfin Figs. 7, 8 and 9, the locking latch 35, is

operated by hand.

The machine herein shown and described is extremely simple, strong and durable and it may be manufactured and marketed at a moderate-expense. 7

What I claimas new and desire tosecure by Letters Patent is Ina drag ofthe class described, front and rear angle bars, connecting bars with which the rear bar is securely connected, means whereby the front bar is pivotally connected with the connecting bars, and means for tilting the front bar, said means including an upright angle bar secured to the front bar in the anglethereof, a lever'secured in the angle of the upright angle bar and a horizontal angle bar secured. on the upright an engaging member on the lever for-the notched bar, and an arm extending from the notched bar and constituting a treadle whereby 1t may be actuated.

In testimony whereof I affix my signature in the presence of two witnesses.
